Your router needs a usb connection slot designed to take a 3G stick. You could try making an adhoc connection from your laptop but if this is going to be a permanent setup I would go with a proper 3G router or mifi which you can carry around in your pocket like a mobile wifi hotspot. Here's some examples: i have a TP-Link MR3220 bought for 30 pounds which is ok. Make sure you get the version 2 of this model to ensure compatibility with W8 if you get it and make sure whatever you get is compatible with your 3G modem model.
